In the Lao PDR, the utilization of modern cooking energy sources, such as LPG and electricity is very limited. While more than 80% of households rely on firewood, charcoal users mainly live in urban areas. Firewood is burned on simple, rudimentary devices causing high emission and significant efficiency losses. In rural areas, daily firewood consumption can be up to 5 kg per day per family (over 2 million tons per year). Further growth on domestic firewood consumption might lead to significant forest degradation.

Since 2012, LIRE is working to promote more efficient means of biomass use by technology design program (Efficient cookstove), policy and marketing research or development of renewable solid fuel based on green waste (green charcoal).

Project:World Bank’s Clean Stoves Initiative (CSI) Phase II,
Impact Assessment study of Households indoor Air Pollution (HAP) in kitchens
Duration:June 2014 – May 2015
Project Partner / Donors:University of California Berkeley,
Berkeley Air Monitoring,
World Bank consultants
Project Description: In Lao PDR, main cooking devices, traditional cookstoves and three-stones fires, are inefficient and emit significant quantities of particulate matter (PM 2.5, PM 10) and carbon moxonide detrimental to the health of the main cooks and the family. In the target survey area, 72 households were provided with Clean Stoves to assess the air pollution in their kitchens before and after intervention.
Project:Low Carbon Development Support in Houamueung and Xam Neua Districts
Duration:2013 – 2015
Project Partner / Donors:KFW
Project Description: The project aimed at supporting various mitigation activities that attempt to reduce deforestation based emissions and forest degradation in target villages in pilot districts.
The study took place in 20 target villages in Houamueung district, resulting in the elaboration of village specific profiles related to low carbon development interventions and required support (cookstoves, small pico-hydro, production of solid biofuel).
Project:Piloting improved woodstove project in Northern Lao PDR and contribution to the development of cookstove standards framework
Duration:2013 – 2014
Luang prabang
Project Partner / Donors:Geres
World Bank
Project Description: The objective of the study was to conduct
(1) a socio-economic baseline assessment of cook stove users in three Northern provinces of Lao PDR (Luang Prabang, Oudomxay and Xiengkhouang) where the main cook stoves used by household are Tao Dum, Tao Thai and Tao Cement;
(2) a test for performance and emissions at Phnom Penh GERES Laboratory;
(3) implement clay testing at LIRE laboratory in order to find the best formulation for mixing clay with additive (rice husk char and sodium silicate) to give the best compromise between mechanical strengths and insulation properties.
Project:Lao PDR Market Assessment - sector Mapping & Intervention options - US AID/ADVANCE
Province:Vientiane Province / Luang Prabang
Project Partner / Donors:Nexant
Project Description:The overall objective of the study was to provide an synthetic vision of the Lao energy context (socio-economic analysis and Rural electrification situation) and stakeholders involved (ADB, GIZ, World Bank, PCIA, and USAID Country Missions).
Project:Preliminary study into Infestation of Sylvynia Cuculata at Elefant Asia elephant sanctuary and possible mitigating actions
Project Partner / Donors:Elefant Asia
Project Description:The study commissioned by Elefant Asia - elephant sanctuary based in the Nam Phui National protected area, Sayabouri Province - aimed at performing an assessment of charcoal conversion potential from an invasive water fern. Indeed, Elefant Asia ground has a lake (roughly 2,000 ha) which is completely infested with an invasive water fern "Sylvina culculata" and continues to grow rapidly. The infestation is creating various ecological (reduce oxygen concentration in water) and logistical problem such as difficulties for local people to across the lake on a boat.
Project:Biomass gasification in Lao PDR
Duration:2007 -2008
Province:Bokeo province / Xiengkouang province
Project Partner / Donors:Phitrust
Project Description:This study aimed to explore the feasibility of biomass gasification (pyrolysis of various biomass sources such as wood, rice husk and bamboo) in Lao PDR in general and for 3 specific sites in the provinces Bokeo and Xiengkouang.. The scope of the study included:
- an analysis of the key actors in the goverment and the relevant policies for biomass gasification;
- technologies and biomass source potential availables
- economic analysis for the implementation of biomass gasification activity
